A nurse is mixing regular insulin and NPH insulin in the same syringe prior to administering it to a client who has diabetes mellitus.
Which of the following actions should the nurse take first?
Inject air into the NPH vial.
Withdraw the NPH insulin from the vial.
Withdraw the regular insulin from the vial.
Inject air into the regular insulin vial.
The Correct Answer is A
The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:
-
Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
-
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
-
Withdraw the regular insulin from the vial : The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
-
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.
This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

Correct Answer is D
Explanation
The correct answer is d
Choice A reason:
Administering filgrastim 12 hours after chemotherapy does not typically require an incident report. Filgrastim is often given at least 24 hours after chemotherapy to avoid the risk of increasing the toxicity of the chemotherapy agents. While the timing is closer than recommended, it does not necessarily constitute an error unless specific instructions for the timing were provided by the prescribing physician.
Choice B reason:
The medication vial sitting at room temperature for 2 hours before administration does not require an incident report. Filgrastim can be left out at room temperature for up to 24 hours before use. This is within the safe handling guidelines for the medication.
Choice C reason:
An absolute neutrophil count (ANC) of 2,500/mm³ is within the normal range, which is typically 1,500-8,000/mm³. Filgrastim is used to increase neutrophil counts in patients with low ANC due to chemotherapy. Since the ANC was not low before administration, this would not necessitate an incident report, although it may prompt a review of the necessity of the medication.
Choice D reason:
Flushing the client's IV line with dextrose 5% in water before and after the medication was administered is not the standard procedure and could potentially lead to medication errors or adverse effects. Filgrastim should be diluted in glucose 5% in water for intravenous infusion, but not used to flush the line. This deviation from the standard protocol is what necessitates an incident report.
Correct Answer is A
Explanation
Epinephrine (adrenaline) is the first-line treatment for anaphylaxis, a severe and potentially life-threatening allergic reaction. Epinephrine works by reducing the body’s allergic response and improving the breathing and circulation of the client. Epinephrine should be given as soon as possible after the onset of anaphylaxis symptoms, using an auto-injector device if available.
Choice B is wrong because replacing the infusion with 0.9% sodium chloride (normal saline) is not enough to treat anaphylaxis. Normal saline can help maintain the blood pressure and hydration of the client, but it does not reverse the allergic reaction or improve the breathing of the client. Normal saline can be given after epinephrine, but not before or instead of it.
Choice C is wrong because giving diphenhydramine IM is not enough to treat anaphylaxis. Diphenhydramine is an antihistamine that can help relieve some of the symptoms of anaphylaxis, such as itching and hives, but it works too slowly and does not address the more serious effects of anaphylaxis on the breathing and circulation of the client. Diphenhydramine can be given after epinephrine, but not before or instead of it.
Choice D is wrong because elevating the client's legs and feet is not enough to treat anaphylaxis. Elevating the legs and feet can help increase the blood flow to the vital organs, but it does not reverse the allergic reaction or improve the breathing of the client. Elevating the legs and feet can be done after epinephrine, but not before or instead of it.
